The depth of the screw block 233 has An upper portion, a lower cutting surface 235, 236 extending outwardly from the rod 22, and a peak 237 at the junction of the upper and lower cutting surfaces 235, 236, wherein the peak 237 is at all points while being located The second tooth segment 232 has a wavy base line α spiral around the rod body 22. The upper and lower cutting faces 235 and 236 of the screw block 233 extend correspondingly. The wavy base line α is spirally wound. Of course, the pitch of the peaks 237 of the adjacent two screw blocks 233 (ie, the slot pitch) may also be set to an unequal width. In this embodiment, the width and width of the slot 234 are taken as an example. Explain. Referring to FIG. 4, when the locking is performed, the second tooth segment 232 is first used for drilling and locking, that is, the screw blocks 233 are alternately arranged in a wavy spiral design, so that the second tooth segment 232 can be staggered. a cutting point, so that the second tooth segment 232 is locked with an enhanced cutting effect, so that the second tooth segment 232 reaches the second tooth segment 232 quickly, labor-saving and reduces the locking torque j, and finally enters the first tooth segment 231 Locking, at this time, the first tooth & 231 also uses the spacers arranged in the interval to maintain a better cutting effect, until the sawtooth screw 2 actually locks the set position, and when the wrong tooth screw 2 locks After the setting position, the screw blocks 233 of the first and second segments are alternately designed, and the locking effect of the 6 • M317508 can be increased. Referring to FIG. 5', a second preferred embodiment of the present invention, the difference of the first embodiment is that the thread of the second tooth segment 232 is divided into the wavy base line α~ghost in an asymmetrically staggered manner. 235, -, column ', that is, in the figure, three pieces of screw blocks 233 are arranged on the same side or three sets of screw blocks 233 as shown in FIG. A staggered pattern formed by one set of screw blocks 233 disposed on the other side, regardless of the manner in which the thread blocks 233 are disposed. The raft is assisted to increase the cutting ability of the second segment 232. Referring to FIG. 7, a fourth preferred embodiment of the present invention is still the same as that described in the first embodiment; in particular, the peak 237 of each of the second blocks 232 is a line. And the tangential line is at an angle Θ with the wavy base line α; of course, the peak 237 can also be a face other than that shown in FIG. 8, and the apex of the screw block 233 is tangent or cut. , are to increase the cutting ability of the actual lock. FIG. 9 is a sixth preferred embodiment of the present invention, which is still the same as described in the foregoing first embodiment; in particular, a liter surface 239 is formed on the side of the peak 237, and the peak 237 of the embodiment is The tangent point indicates that the screw block 233 has a better bearing capacity when it is locked.
